[Pharo-project] Method expressed as symbol, used as argument
by DougEdmunds March 19, 2011

March 19, 2011

It was pointed out that given an instance method MyClass >> doSomething that MyClass do: [:each | each doSomething]. can be expressed as MyClass do: #doSomething. Can someone suggest something to read that explains the usage of # here (#doSomething), the relation of methods to symbols, etc. Trying to wrap my head around it. Thanks. -dae -- View this message in context: http://forum.world.st/Method-expressed-as-symbol-used-as-argument-tp3388864… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] SUnit and Tests inheritance or 'Data' injection
by Stefan Marr March 19, 2011

March 19, 2011

Hi: I have a design problem with my test cases. In my benchmark suite I have a runner class that controls how benchmarks are executed. Now I want to subclass it to provide a runner that automatically finds a reasonable number of iterations for microbenchmarks. Thus, it will first measure the time of a first run and then double the number of iterations until it has some like at least 300ms runtime. Ok, thats the domain design, now the question how do I test that hierarchy with SUnit? It seems like my test hierarchy that parallels the domain hierarchy is not actually working like I would expected it. Thus, my basic test class implements some 9 tests, and my auto-sizing test-class adds two more test. However, when I run the tests, only 11 tests are executed and not 2*9 + 2 = 20 tests. Is there something I am missing? Is there a way that I can force SUnit to also execute the tests of the superclass? Or, something that would actually be nice, is there a way that I can automatically parameterize my tests with data? Then I would not need to us subclassing in my test hierarchy, but could just tell the basic tests to run with all the different runner classes, and for the autosizing runners, I can just run additional tests.

Categories are not packages, if we make every category a package we will end up in a big mess (as groups of these would have lots and lots of dependencies). Already the PackageInfo Packages for Network and Collection (the split into just the class categories - as- packages) was a mistake, purely driven by speed of MC. > - check again the implementation of RPackage and in particular the necessary compatibility layer, because I saw some strange > code. > - check the MC dependency on method category conventions, because some logic is not defined in the right place > like overrides in the MC tools and not in the PackageInfo > - check how a package gets created when loaded: the key question is that there is a problem to rely on categories to > associate classes to packages because we can end up with overlapping (normally the IDE captures the category renames > and change the packages accordingly). > - we should not rely on most-specific-category kind of pattern matching. > > So if you have suggestion please talk now. > > > Stef -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

[Pharo-project] Source in a file format ...
by James Ladd March 19, 2011

March 19, 2011

The Pharo File out format is currently supported by Redline Smalltalk. However, editing a class in a file in "chunk" format is not that pleasant. What would you suggest as a format for source code that is in a file? Avi Bryant of DabbleDB/Twitter fame suggested having a + (class) or - (instance) before a method pattern and just ending the method with a period. What do you think ? for example: - yourself ^ self. Rgs, James.

[Pharo-project] New section in Pharo website for business Re: ZeroMQ bindings for Pharo
by Mariano Martinez Peck March 19, 2011

March 19, 2011

I think Esteban is right. We should create a page/section in pharo-project that shows all the available tools for doing a real, business app. So, we could say something like: Web development: - seaside - aidaWeb - Iliad Persistence - ... - HTTP and networking ... Improving development time - developer tools for pharo - Control version system - Package management system - Web hosting - security Those are some of the things people usually look when starting a project cheers Mariano On Sat, Mar 19, 2011 at 1:41 PM, Esteban Lorenzano <estebanlm(a)gmail.com>wrote: > Hi, > We are starting to have a lot of new cool tools to make really enterprise > projects. > Yes, this needs to be in the book (also with others now absent, like > "riak", etc.)...

[Pharo-project] Porting Visual Works to Pharo
by Guillermo Polito March 19, 2011

March 19, 2011

Maybe this question is out of the scope of this list, but probably someone can help :). As described in some threads, I want to use what's described in: http://scg.unibe.ch/wiki/howtos/portingfromvisualworkstosqueak But when I try to load FileOut30 It doesn't load the Squeak Compatibility classes because it seems I lack the refactoring browser. I've already tried to load some Refactoring Browser from different stores, but it screws my image :). I'm using the community edition of Visual works in windowze. Can someone point me in the right direction? (Let's say I'm not very used to VisualWorks) Thanks! Guille
